"I will be live tweeting the Oscars tonight, but I won't be watching them. WHA!?! That's crazy!" he posted to the social media site. "Question: Do you guys have any suggestions for what I should be doing instead of watching the show?"

"EXCLUSIVE: I heard Kevin Spacey and Harvey Weinstein were going to come disguised as a very tall man in a long trench coat but they got busted by security," he wrote, before calling out Casey Affleck.

Franco has denied sexual misconduct allegations brought forth by five women, while Weinstein has rebutted all allegations of non-consensual sex.

Affleck faced sexual harassment allegations in 2010 in two public civil suits during the production of the mockumentary "I'm Still Here." The suits were settled for undisclosed sums and Affleck has said that the terms of the settlement prevent him from discussing the matter.

Spacey has faced numerous sexual misconduct and assault allegations, but he has remained mostly silent. In a statement to NBC News in November, Spacey's representatives said the actor would take a step back for evaluation, but did not give further details.

In addition to tweeting about Affleck and Franco, Culkin also posted a number of messages about show's host, Jimmy Kimmel.

The actor also sprinkled his Twitter feed with a number of "things I'm doing instead of watching the Oscars," including playing the guitar, cooking ramen noodles and painting his toenails, all while wearing a formal tuxedo.
